Portable Emulator

I'm looking for a portable Emulator solution, some way to play Genesis/Megadrive ROMs on the go.

1) Laptop. You should be able to run a good emulator on a decent laptop and play your ROMs there. Kinda bulky though. What about an old Toshiba Liberetto? Do they have enough power to run a decent Emulator?

2) Palmtop. Palm devices don't seem to have the resolution to run an emulator. Some WinCE devices doo though. I have heard of an emulator that runs on some WinCE handhelds but VERY SLOWLY. How much longer before we get a decent Genesis Emulator for a handheld device?

3) Custom Solution. Is it possible to build an adapter for a Nomad that will play ROMs off of a Compact Flash card? Aren't there some devices that are, in essence, blank Genesis cartridges that you can load ROMs onto?

I think it would be great to take hundreds of Genesis games with you wherever you go. Imagine, play them on the bus, train, airplaine, wating in line. Wherever you like without having to lug around bulky cartridges.

ive seen import sites like Lik-sang.com and they have flashcart writers and blank carts for a bunch of systems (GBC, GBA, SNES, NES and a few others i think), yet they dont have any Genesis cart writers (strange huh?)

i wish someone did make a Genesis cart writer though cuz i missed out years ago to buy Shining Force 1 and 2 and now they are collectors items going for easily over $50 US on ebay!!!!

but 1 thing ive always wondered about is the blank flash carts for the various systems above are REALLY expensive (GBA blank flash carts are over $100 US depending on how much space you want on them)

ive already figured that out kamalot, but a GBA flasher kit with a 128megabit flash cart (the biggest GBA flash carts in existence so far) costs $170 US or so on lik-sang.com, while the flasher by itself costs about $40 US, its still a good buy if you get enough GBA roms but still buying a GBA system and then that flasher kit, thats getting pretty expensive!

and most GBA games are 64megabits in size, meaning you cant cram more then 2 games onto the blank at one time, and just you watch, in a matter of months all the games will come out as 128megabits in size, which is annoying cuz you would have to flash over and over again for whatever game you feel like playing at the time (i much prefer being able to have a bunch of games on 1 cart, much more convenient)

Mike G: I was looking at flash prices, and for the specific chips used in those carts (according to Reiner Ziegler, anyway, and I don't have any reason to doubt him). If anything, I was probably underestimating labor costs.

Erm... "stupid cheap flash cart"? I've got news for you - Flash is more expensive than EPROM, and both have a limited data retention life and write/erase cycle tolerance. I fail to see how EPROM is an advantage unless you intend to make carts dedicated to specific games.
